TECHNICAL CAPABILITIES OF METAL INVESTIGATION AND ISE

METAL MAGNETIC MEMORY METHOD

It combines the capabilities of non-destructive testing, fracture mechanics and general metallurgy.

The main advantages are as follows:

It does not require special magnetizers;

The stress points, which are unknown in advance are to be determined in control process;

It does not require special control surface preparations;

small size of MMM devices.

The main objective of the method is determination of areas and points containing stress zones.

After that the specific defects are determined by the penetrant inspection, ultrasonic testing, magnetic

particle testing, etc.

ULTRASONIC THICKNESS MEASUREMENT

It is used to determine the thickness of the walls of equipment, which is exposed to corrosive and erosive wear in the continuous service.

It is conducted by the ultrasonic thickness tester BULAT-1M («БУЛАТ-1М»).

CONTROL OF METAL HARDNESS

After considering the results of hardness control there is a measurement of the metal mechanical properties change.

The control is conducted by the portable hardness tester of 54-459M, 54-359M type.

VIBRATION CONTROL

It is carryed out in order to determine the bucket exciting frequency.

The control is conducted by the free vibration frequency meter ICHSK-1 (ИЧСК-1), the measured frequency range is from 22 Hz to 17,400 Hz.

PENETRANT AND FLUOROSCOPIC FLAW DETECTION

Allows to identify surface defects such as cracks, pores, etc.

For the purpose of control are used the sets of flaw detection materials of leading global manufacturers.

MULTICHANNEL VIBRATION-MEASURING COMPLEX ATLANT

It is on the basis of a personal computer.

VISUAL INSPECTION CONTROL

Набор ВИК-эксперт.

CONTROL OF METAL MICROSTRUCTURE CHANGE

Determination of changes in the metal structure during continuous operation by the method of metallo graphic replicas on polished areas of 30x30
mm. The research is conducted at steady-state conditions on an optical microscope, such as MIKROMED MET with a CANON set of visualization, which allows to make

the full metallographic analysis of metals in the laboratory conditions without specimen cut-offs.
